반응 단계
1,3-Propanediol (2.9 g, 38.0 mmol) is reacted with 3-isocyanatopropyltriethoxy silane (16.4 g, 76.0 mmol) and 0.2% dibutyltin dilaurate catalyst. The reaction is conducted under nitrogen at room temperature in a glass vessel with mechanical stirring. An exotherm occurs after 15 minutes and the reaction is complete after 2 hours as evidenced by infrared spectroscopy. The following TEOS macromer is obtained ##STR9## as a low viscosity liquid, MW 508.72, which is stable at room temperature.
